  • Various aspects of the technology described herein are generally directed towards a background transfer service that provides platform-level support for applications to queue transfers to run in the background. This ensures that applications can perform appropriate data transfer tasks in the background, without offering applications complete flexibility to run whatever code they want.
  • the background transfer service allows applications to queue requests, cancel requests, check request status and continue transferring (upload / download) content while the application is not running in the foreground.
  • Applications can download content essentially in parallel, e.g., via a round-robin fairness mechanism that provides resources to the applications in a fair way.
  • An application may specify transfer preferences, however policies associated with the background transfer service control what applications can do, e.g., an application may only have some maximum number of outstanding transfers at a time, data transfer may be limited to some size when over cellular and Wi-Fi is unavailable or if external power is absent, a background application may not be allowed to use a 2G/EDGE cellular connection, different actions may be taken when on battery power, low power or when connected to AC / USB charging, and so forth.

This is also available when an application is tombstoned (moved to the background rather than closed, with the operating system maintaining state information for later when the application returns to the foreground).
  • foreground applications can add requests to the background transfer service's request queue; foreground/background applications can find requests in the background transfer service's request queue and remove requests from the background transfer service's request queue.

  • the background transfer service 102 may apply a different policy or have other rules, e.g., to prioritize the foreground application transfer requests over those of background applications, use different limits (or even no limits) and so forth. This also applies when a background application is using the service and gets changed to the foreground application; its queued requests are moved up in priority (other application requests may be paused), limits may be changed or not enforced, and so forth.

  • the background transfer service 102 moves the file from the cache to the application's store when the transfer is successful, e.g., using MoveFile support in the data sharing service 1 10. Note that the MoveFile API does not copy the data when the move is not across different logical volumes.
  • the entertainment download manager 1 14 In response to DownloadManagerCreate, the entertainment download manager 1 14 returns a download ID which the background transfer service saves in memory (download IDs are not valid across reboots) together with the rest of the transfer request parameters. The background transfer service then calls the entertainment download manager 1 14, DownloadManagerStart, and starts the transfer process. [0066] Once the call to the entertainment download manager 1 14 for starting the transfer is successful, the background transfer service saves the request including the target file token ID associated with the request to EDB (corresponding to step 628).

  • a background transfer service client can optionally subscribe to receive transfer progress notifications and an application callback will be made at specific completion points of the transfer.

This will pause the transfers queued in background transfer service thus far, including the waiting, transferring and created transfer states. As opposed to using just the waiting state, this state is useful for an application to distinguish whether the delay of the transfer is deliberate because a first party application (e.g., resource manager application instance manager 1 16) paused the transfer or whether it is accidental due to transfer conditions not being met.

  • the entertainment download manager 1 14 may detect slow and hung transfers by checking whether the transfer rate is below a threshold, so as to consider them as failed and apply retry policies on them. For example, if the transfer rate drops below x kbps on Wi-Fi, the transfer will be paused and resumed at a later time. The entertainment download manager 1 14 will fail transfers that are over 20MB if Wi-Fi is not available with a specific error. In that case, the background transfer service will monitor for Wi-Fi connectivity and requeue the transfers with the entertainment download manager 1 14 when Wi-Fi is back up.

  • the entertainment download manager 1 14 moves a transfer request to a waiting state and starts the transfer when connectivity comes back on. If connectivity does not come back on within a timeout, the transfer is canceled by the entertainment download manager 1 14 and a connection timeout error reported to the background transfer service 102. In that case, the background transfer service will monitor for connectivity and requeue the transfers with the entertainment download manager 1 14 when connectivity is back up.
  • a connection manager chooses from available connections based upon bandwidth.

  • the background transfer service 102 performs monitoring in order to queue requests into the entertainment download manager 1 14, including whether the device has connectivity or not. This is done because the entertainment download manager 1 14 fails a transfer if connectivity is not available in a certain time, (e.g., 1 minute by default). Hence, the background transfer service monitors connection availability. The background transfer service also monitors the device's power state (AC/battery, battery status). [0084] The background transfer service may queue application requests with the same priority with the entertainment download manager 1 14, e.g., background priority (DM_TYPE_CONTENT, DM_PRIORITY_OPPORTUNISTIC), which is the lowest of the three entertainment download manager 1 14 priorities. This is to make sure that third party transfers do not interfere much with first party transfers such as marketplace downloads.

Abstract

La présente invention se rapporte à un service de transfert en arrière-plan qui procure un support de niveau plate-forme à des applications tierces. Ceci a pour but de mettre en file d'attente des transferts de données de telle sorte qu'ils s'exécutent en arrière-plan, y compris lorsque l'application ne s'exécute pas en arrière-plan. Selon la présente invention, des applications peuvent ainsi accomplir des tâches de téléchargement et de chargement en arrière-plan. Cependant, le service de transfert en arrière-plan gère les demandes de transfert de données de sorte à limiter la capacité de chaque application qui s'exécute en arrière-plan à interférer avec des applications qui s'exécutent en avant-plan. En d'autres termes, l'utilisation des ressources est contrôlée sur la base d'une règle, ou plus.
